Hello,
I’m using libraries over WAN and caching thumbnails uses ridiculous amount of bandwidth. It also slows down operation by a lot.
This is also the case for slower hardware such as Raspberry Pi even on LAN.
I’ve disabled “Extract thumbnail and video information” for now, but I would like to keep “extract video information” enabled.
I found discussions regarding this dating back to last decade and XBMC team members even back then stated that it would be preferable to have the 2 settings separate.
